Nice MS-Dos demo

Does run well on 386 (even low end judging by the dosbox cycles). Has few nice effects. I always envision CGA as this 4 color cyan/magenta hell, but I know it's really more than that. I would have thought this is an EGA demo just by screenshots.

Uses the 160x100x16 "mode" trick of 80 column text set to 100 rows (first 2 char lines only), and left/right half block chars. Not the best palette for plasmas, but the default black/white/cyan/magenta palette is nice for vaporwave. :) You could also do an 80x100xmore-than-16 "dithered" color mode using the halftone characters.

Good music, not new but I assume Void was ok with it.

Any chance for a fixed version that would also work on VGA-cards? :)

well done! tested it with PCem 13, runs even on a 286/8Mhz with 512kb RAM .. lot of CGA snow in the emulation, maybe different on real hardware ..

Thanks for the votes! This was rushed (of course). I haven't had a chance to test it on real hardware yet, hopefully over the xmas break. I think it needs a fast 286 - I gotta work on getting those routines faster though. I'm interested in exploring CGA a bit more and want to try some dithering tricks using the halftone characters! I have a final version with a bunch of optimisations which I'll get uploaded asap.

Love the "plasma"! Great effort! Hope we see the final version with optimized routines someday.

It probably works on real hardware just fine, so wouldn't worry about that. But it currently requires a 286-12 to be watchable, so some optimized routines would help get it down to the 8086 level (which is the true target for this kind of thing, as most 286s had EGA or better).
